In the lithium battery PACK customization industry, choosing a reliable supplier means long-term product quality and fast technical response. As a manufacturer with our own factory and an in-house PACK structure engineering team, Qiwang Energy provides end-to-end solutions for domestic and international clients — from cell selection and BMS design to final PACK assembly.

Advantage 1: PACK Structure Design Capability — From BOM to Final Assembly, Fully In-House

Qiwang Energy has a dedicated PACK structure engineering team, which is the core moat distinguishing us from trading companies:

• BOM autonomous design: from series/parallel calculation → cell C-rate verification → structural component selection, all handled by our internal engineering team
• PACK automated design system: self-developed battery_design_core.py core module covering three functions: electrical calculation, cost estimation, and physical estimation
• Pack simulation & validation: tools including ISEAFrame, liionpack, PyBOP, and PyECN for simulation to ensure design accuracy
• Modular structure: expandable and easy-to-maintain module design with low upgrade costs later

Advantage 2: BMS Technology — Self-Developed + Multi-Brand Flexibility

The BMS is the “brain” of a battery pack. Qiwang Energy offers multi-tier solutions:

Advantage 3: Multi-Brand Cell Resource Integration

Qiwang Energy does not bind to a single cell supplier — instead, we integrate industry-leading resources:

• Jikong (极空科技): 180Ah+ LFP cells, high safety and long cycle life
• CATL (宁德时代) Grade-A cell channels: catering to different customer brand preferences
• 314Ah large-capacity cells (CBA71173207EES-314Ah): enabling higher energy density for ESS / forklift applications
• Fully tested before every shipment: voltage consistency, insulation resistance checks

Advantage 4: Own Factory Manufacturing Strength

In-house PACK factory = full-process control:

• Fully automated welding lines: laser welding (not manual spot welding) for connection reliability
• Class 1000 cleanroom: PACK assembly in Class 1000+ cleanroom to reduce short-circuit risk
• IQC → IPQC → OQC full inspection chain: every pack tested before shipment
• Production capacity: capable of large-order on-time delivery

Advantage 5: Fully Certified, Global Delivery Capability

The compliance questions most important to export customers are comprehensively covered:

• UN38.3 full test series (T1-T8): CNAS/ILAC-accredited lab reports
• CE / RoHS directive compliance: EMC + LVD, EU market entry threshold
• IEC 62619 industrial safety standard: forklift / ESS dedicated battery certification
• UL 2580 / UL 1973 / UL 9540A: US market mainstream certifications, including thermal runaway propagation testing
• ISO 9001 / ISO 14001: quality management + environmental management system certifications
• Complete shipping documentation: UN38.3 report, MSDS/SDS (latest versions), DGD dangerous goods declaration

Advantage 6: Custom Solutions & Local Service

Deep customization for different scenarios and customer needs:

• Voltage / Capacity / Dimensions matched to equipment: reverse-engineering optimal solutions based on your specs (e.g., QC-25.6V280AH / QC-51.2V280AH / QC-76.8V460AH)
• BMS communication protocol integration: CAN/J1939 compatibility with your vehicle BMS / host system
• Harsh environment adaptation: -40°C low temp, high temperature, high altitude, humid — proven experience in multiple scenarios
• Second-life & recycling solutions: retired batteries comply with environmental regulations, with second-life utilization plans
